Description

Detailed Description of the Invention [Industrial applications]

The present invention mainly relates to an apparatus for heating waste synthetic resin in a heating pot to turn it into oil.

[Prior art]

The thermoplastic synthetic resin can be liquefied by heating, liquefying, vaporizing in a gaseous state, and cooling. Utilizing this fact, a device for heating waste synthetic resin to turn it into oil has been developed. For example, Japanese Examined Patent Publication No. 61-17879 discloses an oiling device equipped with a heating pot or a screw conveyor. An oiling device equipped with a heating pot continuously supplies waste synthetic resin to the heating pot with a screw conveyor. The heating pot is heated by the heater. The heating pot heats the supplied waste synthetic resin to melt and vaporize it. The vaporized synthetic resin flows into the condenser and is cooled in the condenser to become liquid oil. An oiling device having a screw conveyor is provided with a heater on the outer periphery of the screw conveyor. The heater heats the outer circumference of the screw conveyor. The waste synthetic resin is transferred by a heated screw conveyor, and is melted and vaporized into a gas state during the transfer. The gas is sent to the condenser through piping. The condenser liquefies the gas into oil. Furthermore, JP-A-51-22776 and JP-B-52-1
Japanese Patent No. 949 also describes an oil liquefaction device for waste synthetic resin. This oiling device includes a melting tank for melting the waste synthetic resin and a reaction tank for supplying the molten synthetic resin to vaporize it. Furthermore, Japanese Patent Application Laid-Open No. 60-49086 describes an oiling device for uniformly heating a heating pot for heating and decomposing synthetic resin. In the oilification device disclosed in this publication, a heating pot is arranged in a heating furnace. Between the heating furnace and the heating pot,
The heating medium is filled in order to uniformly heat the heating pot. Sand, potassium nitrate, sodium nitrate or the like is used as the heat medium. This oiling device uniformly heats the heating pot by heating the heating pot via the heat medium.

[Problems to be Solved by the Invention]

The oiling device using a furnace has a feature that the synthetic resin can be melted and vaporized by using the oiled oil as a fuel. For this reason, this oiling device has a feature that fuel for heating the synthetic resin is not particularly consumed. The oil consumed for the melt vaporization of waste synthetic resin is about 10 to 20% of the oil oilified from the synthetic resin. However, the method of heating the heating kettle in the furnace has a drawback that a large amount of dregs remain in the heating kettle without being liquefied and the amount of oil to be liquefied is reduced due to an increase in gas components. It is extremely important for this kind of apparatus to reduce the amount of residue in the heating pot and increase the amount of oil to be oiled. It takes a lot of time to remove a large amount of debris from the heating pot, and it is also troublesome and costly to dispose of it. Furthermore, the fact that the amount of oil that is oiled is small means that
Synthetic resin cannot be reused effectively. In the oilification device that heats the heating kettle in the furnace, the amount of dregs is large and the amount of oil to be oiled is small because it is difficult to control the temperature distribution in the heating kettle to an ideal state. . That is, when a heating pot is provided in the heating furnace and the bottom of the heating pot is heated by the burner, the heating pot melts and vaporizes the synthetic resin in the following state. The synthetic resin supplied to the heating pot accumulates at the bottom. The heating pot is heated by a burner from the bottom. The heated synthetic resin melts at the bottom of the heating pot. That is, molten synthetic resin accumulates at the bottom of the heating pot. The molten synthetic resin is further heated and vaporized. The vaporized synthetic resin fills the upper part of the heating pot. Molten synthetic resin is accumulated at the bottom of the heating pot.
Therefore, the temperature rise of the bottom of the heating pot is limited by the heat of vaporization of the synthetic resin. Normally, the temperature of molten synthetic resin is about 35
It is 0 to 450 ° C. The upper part of the heating pot filled with gas is heated to a high temperature. This is because the synthetic resin in the molten state cannot be maintained at a constant temperature. The heating pot whose temperature has risen high heats the gas inside to a high temperature. The gas heated to a high temperature becomes carbon and adheres to the inner surface of the heating pot, and the thermal decomposition increases the amount of low-distillation gas components. Therefore, the oiling device that heats the heating kettle in the furnace has a drawback that a large amount of dust remains in the heating kettle and the amount of oil to be oiled is reduced. The oiling device in which the heating medium is filled between the heating pot and the furnace is
The heating pot can be heated uniformly. However, since the heating pot is heated via the heating medium filled in the heating furnace, there is a drawback that the overall thermal efficiency is low and a large amount of oil is consumed as fuel. Further, in order to uniformly heat the heating pot via the heating medium, it is necessary to sufficiently convect the heating medium in the furnace, but it is also difficult to sufficiently convect the heating medium. The present invention was developed for the purpose of solving these drawbacks of the prior art. Therefore, an important object of the present invention is to provide a synthetic resin oiling device capable of reducing the residue left in the heating pot and increasing the amount of oil to be oiled.

[Means for solving conventional problems]

In order to achieve the above-mentioned object, the oil liquefying apparatus for synthetic resin of the present invention has the following constitution. The oilification device for synthetic resin includes a heating pot 2, a stirring member 3 for stirring the synthetic resin supplied to the heating pot 2, and a heating pot 2.
A heating furnace 4 for heating the heating furnace 4 and heating the heating kettle 2 in the heating furnace 4 to melt and vaporize the synthetic resin supplied to the heating kettle 2; With the configuration of. (A) The stirring member 3 has a blade 10 for stirring the lower portion of the stirring member 3. (B) The heating pot 2 has a lower portion inside the heating furnace 4 and an upper portion outside the heating furnace 4. (C) In the heating pot 2, the upper part of the portion disposed inside the heating furnace 4 is insulated by the heat insulating member 12. The heating pot 2 has different heating states in the upper part, the intermediate part, and the lower part. The lower part of the heating pot 2 is heated in the heating furnace 4 with its outer surface positioned inside the heating furnace 4. Furthermore, inside the lower part of the heating pot 2, the stirring member 3
It is agitated by blades 10 of. The middle of the heating pot 2 is inside the heating furnace 4 and is insulated by a heat insulating member 12. The upper part of the heating pot 2 is located outside the heating furnace 4 and is not heated inside the heating furnace 4. Further, the oilification device for synthetic resin according to claim 2 of the present invention is a heat insulating member for insulating the heating pot 2 inside the heating furnace 4.
The lower end of 12 is located below the upper end of the blade 10 that stirs the inside of the heating pot 2. The inner surface of the heating pot 2 which is insulated at the lower end of the heat insulating member 12 is configured to be agitated by the blade 10.

[Action]

Referring to FIG. 1, which shows the preferred embodiment of the present invention, the operation of the synthetic resin oiling apparatus will be described. A synthetic resin is supplied to the heating pot 2. When the synthetic resin is first supplied to the heating kettle 2, it is preferable to supply pre-oiled oil. That is, a part of the synthetic resin is immersed in the oiled oil. When the synthetic resin is supplied in this state, the synthetic resin immersed in oil can be efficiently heated and melted. The heating pot 2 whose bottom is heated in the heating furnace 4 heats the supplied synthetic resin. The synthetic resin heated in the heating pot 2 is melted at the bottom. Part of the molten synthetic resin is vaporized into a gas state, and the gas is transferred to the condenser 5 through the pipe. The condenser 5 liquefies the supplied gas into oil. When the synthetic resin becomes a gas and is discharged from the heating pot 2, the synthetic resin is further supplied and melted and vaporized. The apparatus of the present invention for liquefying the synthetic resin in this state liquefies the synthetic resin by making the temperature distribution in the heating pot unique. That is, as shown in FIG. 1, the heating pot has an upper part located outside the heating furnace 4 so that the heating furnace 4 does not directly heat the heating furnace. Furthermore, as shown in FIG. 1, the middle of the heating pot 2 is located inside the heating furnace 4 and is insulated by the heat insulating member 12. Since the upper portion of the heating pot 2 is disposed outside the heating furnace 4, this portion is not directly heated by the flame of the heating furnace 4. Therefore, the upper portion of the heating pot 2 located outside the heating furnace 4 can be designed to have a low temperature. In the conventional oiling device in which the entire heating kettle is arranged in the heating furnace, the upper temperature of the heating kettle becomes high. When the temperature of the upper part of the heating pot increases, carbon adheres to the inner surface of this part. This is because the vaporized synthetic resin gas is heated to a higher temperature in the upper part of the heating pot to become carbon. Carbon adheres to the inner surface of the heating pot as dust. However, the oiling device of the present invention prevents carbon from adhering to the upper part of the heating pot by the unique structure. This is because the heating pot is divided into a lower portion, an intermediate portion, and an upper portion to optimize the heating state. The lower part of the heating pot is heated to a high temperature in the heating furnace. The middle part is inside the heating furnace, but is not heated like the lower part because it is insulated by the heat insulating member. Since the upper part of the heating pot is discharged to the outside of the heating furnace, the heating amount becomes smaller than that in the middle part. The heating pot of this structure efficiently heats the supplied synthetic resin in the lower part to melt and vaporize it. The vaporized synthetic resin gas fills the inside of the heating pot. The synthetic resin gas filling the heating kettle contacts the inner surface at the top of the heating kettle. The synthetic resin gas contacting the inner surface of the upper part of the heating pot is liquefied again in this portion. This is because the upper part of the heating pot is outside the heating furnace and the temperature is low. The synthetic resin liquefied in the upper part of the heating pot is
Run down along the inner surface of the heating kettle. Therefore, the intermediate portion of the heating pot is a portion where the liquid synthetic resin flows down. The liquid synthetic resin flowing down keeps the intermediate inner surface of the heating pot wet and prevents carbon from adhering thereto. The liquefied synthetic resin in the middle flows down in a liquid state because this portion is inside the heating furnace and is insulated by the heat insulating member.

However, the examples shown below exemplify an oiling device for embodying the technical idea of the present invention, and the device of the present invention has the following materials, shapes, structures, and arrangements of components. Not specific to structure. The device of the present invention has various modifications within the scope of the claims. Further, in this specification, for easy understanding of the claims, the numbers corresponding to the members shown in the examples are referred to as "Claims of the claims" and "Means for solving the conventional problems. It is added to the members shown in the "column" and the "column of action". However, the members shown in the claims are not limited to the members of the embodiment. The synthetic resin oilification apparatus shown in FIG.
And a supply means 20 and a condenser 5. The heating reaction means 1 heats the waste synthetic resin in a closed space. The heating reaction means 1 includes a closed heating pot 2, a stirring member 3 that stirs the synthetic resin supplied to the heating pot 2, and a heating furnace 4 that heats the heating pot 2. The heating pot 2 is composed of a pot body 2A and a lid plate 2B. The hook main body 2A has an open upper end, and the opening at the upper end is closed by a cover plate 2B. The hook body 2A has a circular horizontal cross section. That is, the upper portion of the shuttle main body 2A has a cylindrical shape, and the bottom plate has a spherical shape. In the kettle body 2A having this shape, the stirring member 3 for stirring the synthetic resin can be brought close to the inner surface, and the synthetic resin can be prevented from adhering to the inner surface of the kettle body 2A. On the outer surface of the bottom plate of the pot main body 2A, heat absorbing fins 7 are fixed so as to efficiently absorb heat from the combustion gas of the burner. A radiating fin 30 for forced cooling is fixed to the upper portion of the hook main body 2A. The radiating fins 30 protrude to the outer periphery of the shuttle body 2A and are fixed in a flange shape. Radiation fin
30 is also used as a flange for connecting the cover plate 2B. Therefore, the lid plate 2B is connected to the hook body 2A by a set screw that penetrates the heat radiation fins 30 of the hook body 2A. The heating pot 2 has an upper portion protruding outside the heating furnace 4.
When the heating pot 2 is projected outside the heating furnace 4 in this state, the height (h) of the protruding portion is 10 to 50% of the total height (H) of the heating pot. Further, preferably, the protruding portion is 15
~ 40% The lid plate 2B has a gas transfer pipe connected to the lid plate 2B. The gas transfer pipe 8 is connected to the condenser 5. The stirring member 3 includes a rotating shaft 9, blades 10, and a drive motor 11
It has and. The rotary shaft 9 is rotatably supported by vertically and airtightly passing through the center of the lid plate 2B of the heating pot 2. A blade 10 is fixed to the lower end of the rotary shaft 9.
The blades 10 are radially fixed to the rotary shaft 9. Feather 10
Has a shape in which the outer periphery approaches the inner surface of the heating pot 2.
The gap between the outer peripheral edge of the blade 10 and the inner surface of the heating pot 2 is 1 to 100 m.
It is adjusted to m, preferably 3 to 50 mm. Since the blade 10 having this shape can scrape off the synthetic resin adhering to the inner surface of the heating pot 2, foreign matter adhering to the inner surface of the heating pot 2 can be removed. Further, the gas stirring blade 6 is fixed to the upper part of the rotating shaft 9. The gas stirring blade 6 is arranged at a position higher than the molten synthetic resin level. The gas stirring blade 6 stirs the atomized or vaporized synthetic resin in the pot main body 2A. As described above, the heating reaction means provided with the gas stirring blade 6 has a feature that the atomized or vaporized synthetic resin temperature is made uniform, the generation of carbon is reduced, and the oiling amount is increased. In the heating pot 2 shown in FIG. 1, the heat insulating member 12 insulates the upper portion of the portion disposed inside the heating furnace 4 below the portion positioned outside the heating furnace 4. The heat insulating member 12 is provided to make the temperature distribution inside the heating pot 2 uniform. The heat insulating member 12 suppresses the transfer of thermal energy from the flame burning in the heating furnace 4 to the heating pot 2. In the heating pot 2 of this structure, the bottom plate is heated by the flame, the transfer of heat energy is suppressed in the middle, and the upper part is radiated to make the internal temperature uniform. The supply of heat energy is suppressed on the inner surface of the heating pot 2 on which the heat insulating member 12 is stretched, as compared with the bottom portion. Therefore, less carbon is attached to the inner surface of this portion. As shown in FIG. 1, the blade 10 of the stirring member 3 is attached to the heat insulating member.
By designing it higher than the lower edge of 12, the amount of foreign matter adhering to the inner surface of the heating pot 2 can be reduced. In a normal use state, the synthetic resin level of the heating pot 2 changes. The reason is that the supply amount of synthetic resin is controlled by the internal temperature. When the temperature of the molten synthetic resin in the heating pot becomes higher than the set value, the synthetic resin can be supplied to lower the temperature. Supplying synthetic resin raises the level of molten synthetic resin. Further, as the synthetic resin supplied to the heating pot 2 is melted and vaporized and sent to the condenser 5, the synthetic resin level decreases. The synthetic resin level in the heating pot also varies depending on the output of the burner heating the heating furnace 4 and the set temperature. When the burner output is increased and the set temperature is decreased, the synthetic resin level increases. On the contrary, if the burner output is reduced and the set temperature is increased, the synthetic resin level decreases. The optimum value of the molten synthetic resin level in the heating pot is the first
As shown in the figure, it is in the vicinity of the lower edge of the heat insulating member 12. The supply amount of the waste synthetic resin, the output of the burner, and the temperature of the molten synthetic resin are controlled so that the molten synthetic resin level is around this. The rotary shaft 9 is connected to a drive motor 11 and is rotated by the drive motor. The heating pot 2 contains zeolite, a metal catalyst or the like so that the waste synthetic resin can be efficiently oiled by heating. Nickel or stainless steel is used as the metal catalyst. Rotating shaft 9
The blade 10 may be made of a metal catalyst such as nickel or stainless. The condenser 5 cools the gas component heated in the heating pot 2 to liquefy it into oil. The condenser 5 is connected to an oil conversion tank 22 that stores liquefied oil. The waste synthetic resin is supplied from the supply means 20 to the heating pot 2. As the supply means 20, any mechanism capable of supplying the synthetic resin while being shielded from the outside can be used. The heating furnace 4 has a structure that can be divided into upper and lower parts. The heating furnace 4 of this structure has a feature that the lower heating furnace is removed and the pot main body 2A can be easily maintained and inspected. A burner 31 is attached to the heating furnace 4. The burner 31 heats the pot main body 2A by burning the oil obtained by converting the waste synthetic resin into oil. Therefore, no extra fuel is needed. The supply means 20 shown in FIG. 1 includes a supply cylinder 13 for supplying synthetic resin to the heating kettle 2, a plurality of opening / closing valves 14 provided on the supply cylinder 13 for cutting off air and supplying waste synthetic resin, and opening / closing. And a control member 15 for controlling the open / closed state of the valve 14. In the supply cylinder 13, the waste synthetic resin is dropped to heat the reaction means 1
Is vertically connected to the lid plate 2B of the heating pot 2 so as to be supplied to the heating pot 2. The supply cylinder 13 shown in FIG. 1 is provided with a gate valve 18 at the upper end. Below the gate valve 18, two-stage series open / close valve
14 are provided. The supply cylinder 13 has a supply chamber 19 between the gate valve 18 and the upper opening / closing valve 14. 2-stage open / close valve 14
A temporary storage chamber 16 is provided between. The gate valve 18 includes an opening / closing plate 18A that moves laterally with respect to the supply cylinder 13, and a linear cylinder 18B that moves the opening / closing plate 18A. The opening / closing plate 18A is provided so as to move laterally through the supply cylinder 13. In the drawing, the opening / closing plate 18A is moved to the right and the supply cylinder 13
Closed and moved to the left to open the valve. The on-off valve 14 includes a valve seat 23, a rotary valve 24, and a reduction motor 25 that rotates the rotary valve 24. The valve seat 23 is fixed to the supply cylinder 13. The rotary valve 24 is fixed to the rotary shaft 26. The rotary shaft 26 penetrates the supply cylinder 13 in an airtight manner and is attached to the supply cylinder 13 via a bearing. As shown in FIG. 1, the rotary valve 24 comes into close contact with the valve seat 23 and closes when rotated upward. The rotary valve 24 is opened when it is rotated 90 degrees from the position shown in the figure. The valve seat is formed in a shape that comes into close contact when the rotary valve rotates upward. The opening / closing valves 14 provided above and below the temporary storage chamber 16 have the same shape. The volume of the temporary storage chamber 16 is designed to be substantially equal to or slightly larger than the supply chamber 19. This is because all the waste synthetic resin stored in the supply chamber 19 is temporarily supplied to the storage chamber 16. On the inner surface of the supply cylinder 13 which constitutes the temporary storage chamber 16, a metal catalyst is
27 is fixed. The metal catalyst 27 efficiently oilizes the waste synthetic resin heated in the temporary storage chamber 16. Further, in the temporary storage chamber 16, in order to preheat the waste synthetic resin stored therein and to close the on-off valve 14 surely,
Heated oil is supplied. The heated oil is supplied from the heating oil supply pipe 17. Therefore, the heating oil supply pipe 17 is connected to the temporary storage chamber 16. The heating oil supply pipe 17 temporarily supplies the oil, which has been oiled from the synthetic resin and is in a heated state, to the storage chamber 16. The heating oil supply pipe 17 is
The heated oil supply pipe 17 is connected to the outlet of the condenser 5 so that heated oil can be supplied. The heating oil supply pipe 17 connected here can supply the heating oil to the temporary storage chamber 16 when the supply valve 28 is opened. in this way,
When a part of the oil obtained by converting the waste synthetic resin into oil is temporarily supplied to the storage chamber 16, it is not necessary to separately heat the oil. However, as the oil supplied from the heating oil supply pipe 17 to the temporary storage chamber 16, it is possible to supply an oil other than the waste synthetic resin oilized. Heavy oil, light oil, kerosene, or the like can be used as the oil heated and supplied from the heating oil supply pipe to the temporary storage chamber. Further, at the beginning of using this apparatus, the oil obtained by oiling the waste synthetic resin cannot be obtained from the heating reaction means 1. Therefore, at the beginning of using this device, an oil different from the oiled oil is heated and supplied to the temporary storage chamber. A discharge pipe is connected to the upper part of the temporary storage chamber 16. The exhaust pipe 29 exhausts the gas in the temporary storage chamber 16. Open / close valve 14
When oil is supplied to the temporary storage chamber 16 with the valve closed, gas corresponding to the amount of oil and the amount of gas generated from the waste synthetic resin by the heating oil is discharged. When high temperature oil is supplied, a part of the waste synthetic resin vaporizes in the temporary storage chamber and becomes gas. This gas more efficiently disposes of residual air in the temporary storage chamber. The temperature of the oil supplied from the heating oil supply pipe 17 to the temporary storage chamber 16 is preferably adjusted within the range of 150 to 200 ° C. The control member 15 that opens and closes the open / close valve 14 includes the open / close valve 14 and the supply valve.
It controls the open / closed state of the gate valve 18 and the gate valve 18. The supply valve 28 is opened with the upper and lower open / close valves 14 closed, in other words, with the temporary storage chamber 16 airtightly closed,
The heated oil is supplied to the temporary storage chamber 16. The open / close valve 14 is provided by opening one of the upper and lower sides so that the supply cylinder 13 does not open the heating reaction means 1 to the atmosphere.
The waste synthetic resin supplied to 13 is supplied to the heating reaction means 1. When the upper opening / closing valve 14 is opened, the waste synthetic resin is supplied from the supply chamber 19 to the temporary storage chamber 16. When the lower opening / closing valve 14 is opened, waste synthetic resin is supplied from the temporary storage chamber 16 to the heating reaction means 1.
